Title: Filter with a fastening device for a coffee-making apparatus
Inventor: JOERGENSEN CARSTEN
IPC: A47J31/44
Filed: 2000-12-08
Abstract: With respect to a filter with a fastening device for a coffee-making apparatus of the type where water is brought to a boil in a closed container, whereupon the water is pressed through a riser pipe into a funnel, where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container through a filter placed at the outlet of the funnel, where the filter is fastened by means of a fastening device which reaches through the riser pipe, the objective is to provide a filter where the aroma and flavour of the ground coffee is exploited as well as possible and where the filter offers a comparatively large filter surface for the finished coffee, and where the filter can easily be removed from the funnel and cleaned with a view to further coffee-making. Moreover, the filter must be easily replaceable by dismantling the handle and locking clip and fitting these on a new filter. According to the principles of the present invention, this objective is met by a filter (1) equipped with a centrally fitted handle (10), which extends into the funnel (2); where the filter (1) is held in the riser pipe (5) by means of a centrally fitted locking clip (4) with locking devices (6) which fit corresponding locking devices (7) inside the riser pipe (5) at an appropriate distance from the filter (1), and where the handle (10) and locking clip (4) are joined by means of appropriate devices (8) which extend through the filter (1).

Title: Solid state lamp
Inventor: TARSA ERIC J
IPC: F21V29/505
Filed: 2000-11-08
Abstract: The invention provides a new solid state lamp (10) emitting a light useful f or room illumination and other applications. It comprises a solid state Light Source (12) which transmits light through a Separator (14) to a Disperser (1 6) that disperses the light in a desired pattern and/or changes its color. In o ne embodiment, the Light Source (12) is a blue emitting LED operating with current high enough for room illumination, the Separator (14) is a light pip e or fiber optic device, and the Disperser (16) disperses the light radially a nd converts some of the blue light to yellow to produce a white light mixture. The Separator (14) spaces the Light Source a sufficient distance from the Disperser (16) such that heat from the Light Source (12) will not transfer t o the Disperser (16) when the Light Source (12) is carrying elevated currents necessary for room illumination.

Title: Synchronised data delivery
Inventor: EVANS PAUL ANDREW
IPC: H04L29/06
Filed: 2001-03-06
Abstract: A data distribution system provides capability for synchronised delivery of data elements to each of a set of receivers In the system, a number of forwarding computers are linked together in a predetermined configuration by a communications network. An originating forwarding computer receives a data element from a source and forwards it to one or more predetermined destination forwarding computers of the system for delivery to receivers. Each forwarding computer operates a cyclical monitoring process to measure at least one characteristic known to contribute to delay in transferring a data element between forwarding computers, calculating the maximum expected delay for each cycle. On forwarding a data element, an originating forwarding computer calculates a prescribed time for delivery to a receiver by a destination forwarding computer taking account of the maximum expected delay at that time, writing the prescribed delivery time into the data element being forwarded. The system is adaptive to varying network performance in maintaining synchronised delivery.

Title: Wet seat protection for air bag control occupant detection
Inventor: SHIEH SHIUH-AN
IPC: B60R21/16
Filed: 2002-09-19
Abstract: A passenger detection system is provided. The passenger detection system utilizes an oscillation circuit that causes an antenna electrode to emit an electric field that is disrupted by the electrical characteristics of an object placed on the scat. This disruption alters the current and phase of the signal in the antenna electrode. By comparing the current flowing in the antenna electrode and/or the difference between the phase of the signal in the antenna electrode and the oscillation circuit output signal with predetermined threshold values, it is possible to detect the presence of a passenger in a reliable and indepensive manner.      Environmental sensors are used to make the determination more accurate.   Humidity, moisture and/or grounding condition arc detected and used to alter processing, values or calculations.

Title: Radio lan system and radio lan system signal collision evading method
Inventor: HIRANO JUN
IPC: H04L12/28
Filed: 2002-03-06
Abstract: A radio LAN system and a radio LAN system signal collision evading method capable of evading signal collision between a radio LAN system starting communication periodically and a radio LAN system starting communication after waiting for an empty communication path. When a scheduler block (6) recognizes presence of a non-signal interval between a downlink phase and an uplink phase upon scheduling a communication frame, the scheduler block (6) arranges an NAV  setting signal after the downlink phase so as to cover the non-signal interval in accordance with an instruction from a NAV setting signal generation block (8), thereby performing scheduling and transmission. Thus, in the non-signal interval, no data transmission is performed by a radio LAN system station of the IEEE 802. 11a standard, thereby evading signal collision in the uplink phase period.

Abstract: A system and method are disclosed that improve automatic speech recognition in a spoken dialog system. The method comprises partitioning speech recognizer output into self contained clauses, identifying a dialog act in each of the self contained clauses, qualifying dialog acts by identifying a current domain object and/or a current domain action, and determining whether further qualification is possible for the current domain object and/or current domain action. If further qualification is possible, then the method comprises identifying another domain action and/or another domain object associated with the current domain object and/or current domain action, reassigning the another domain action and/or another domain object as the current domain action and/or current domain object and then recursively qualifying the new current domain action and/or current object. This process continues until nothing is left to qualify.
